8 Claims.

My invention relates to an improvement in gas burners and an assemblytherefor.

'Ihe objects of my invention are; to provide a gas burner that is easyto assemble, easy to make repairs or replacements, and a burner thatwill operate on low gas pressure andv at the same time have a highefciency.

Referring to the drawings; Fig. 1 is a side view of my gas burner. Fig.2 is an end view of Fig. 1. Fig. 3 is a plan view of Fig. 1 with one ofthe burners removed for convenience of illustration. Fig. 4 is asectional View of the burner supporting frame as seen from the lineIV-IV in Fig. 3. Fig. 5 is a sectional view of the burner and assemblyas seen from the line V-V in Fig. 3; Fig. 6 is a sectional view of theburner as seen from the line VI-VI in Fig. 5. Fig. 7 is a sectional Viewof the burner as seen from the line VII- VII in Fig. 5.

The drawings show a gas burner having two burner units A and B, howeverit is understood that the burner may be made with any number l of burnerunits such as one, two, four, six, eight,

ten, twelve or more as desired.

25. In the drawings is shown a gas burner frame 10 supported on legs orstandards 11 and 11' between which is a gas manifold 12 whichis to besupplied with gas through a pipe 13 which connects to the manifold 12 asshown in Figs. 2, 3, and 5. The frame 10, legs 11 and 1l and mani foldare made integrally or all in onecasting. At spaced intervals on theframe 10 are upwardly projecting flange like elements 14, said angesbeing short and right angled in shape and ,inte grally connected to theframe element 10 and positioned rectangularly with respect to each otherto receive the four corners 'of a rectangular shaped burner and 15seated' therein, by which means the said burners are spaced apart toprovide. an air circulating means between the said burners. In 'thecorners of said upward projecting flanges 14 are portions 16 raisedabove the frame element 10 and on which rest the four corners of theburner. This provides an air space 1'7 between the bottom of the burnerand the frame 10, and the burners 15 and 15 set loosely upon theportions 16 above described, each burner being independent of the otherand separately removable. The manifold is provided with removable gasjets 18, one for each burner, said gas jets being threaded into themanifold as shown in Fig. 5. These gas jets are provided with a hole 19for the gas to jet through from the manifold 13. These jets may be madewith different size holes 19 and the jets may be removed from themanifold 12 and be replaced with jets having a different size hole suchas is necessary for the proper function of the burner on the gaspressure being used.

The burner is composed of a box like unit having four sides 20, 20'; 20,20' and a base 21, cast integrally. The base 21 carries a Venturi tubeelement 22 which registers over the jet Y18 in the manifold 12. The baseof the Venturi tube 22 extends below the base 21, while the top of thetube 22 extends a considerable distance above the base 21.

The top cover of the box just described, is an inverted box having fourside elements 23, 23', 23, and 23" each cut away as at 24 as gas portsand the corners such as 25 thus formed act as legs resting on the base21 as a support for the inverted box. The top of this inverted box has acover 26 upon the under side of which is formed a portion of a sphericalelement 27` which regisd `ters above the upper end of the tube 22. The

cover 26 is provided with an outwardly projecting ange 28, 28', 28" and28 extending around the four sides of the inverted box to meet the upperedge of the walls 20, 20', 20, 20', of the rst box like elementdescribed. 'I'hese flanges are provided with slots 29, 30, 31, 32, 33and 34, and cut away portions to form slots 35, 36, 3'7, 38, 39 and 40,between the anges 28, 29, and 31 and the side walls 20, 20', 20" and 20"of the rst described box like element, said slots functioning as gasports, attention being drawn to the blank spaces 41, 42, 43, 44, and 46which provide a space for afsecondary air supply between the gasescoming from the slots adjacent thereto.

The gas under pressure received in the manifold 12 passes through thejet hole 19 where it and air .enter the tube 22 and pass upwardlystriking the top elements 27 and 26 and travel downwardly in the' seconddescribed box like ele-- ment andY pass through the ports 24 and thentravel upvka'rdl'y' in the rst described box like element and vpass outthrough the slots 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39 and 40where combustion is taking place and secondary air is being suppliedbetween and to the flames through the spaces at 41, 42, 43, 44, 45, and46 thereby insuring complete combustion of the gases being emitted fromthe burner. During the course of travel of the gas and air through theburner as above described the gas is thoroughly mixed with the air andagain supplemented with air at the point of emission from the burnerwhich provides an ideal condition of the fuel for combustion and permitslOl the burner to be operated on low1 pressure gas without sputtering orback flashes.

Such modifications of my invention may be employed as lie within thescope of the appended claims without departing from the spirit orintention of my invention. Now having fully described myinvention, whatI claim as new and desire to secure by Letters Patent is;
